Steven Pinker describes how that went:
> "As a young teenager in proudly peaceable Canada during the romantic 1960s, I was a true believer in Bakunin's anarchism. I laughed off my parents' argument that if the government ever laid down its arms all hell would break loose. Our competing predictions were put to the test at 8:00 a.m. on October 7, 1969, when the Montreal police went on strike. By 11:20 am, the first bank was robbed. By noon, most of the downtown stores were closed because of looting. Within a few more hours, taxi drivers burned down the garage of a limousine service that competed with them for airport customers, a rooftop sniper killed a provincial police officer, rioters broke into several hotels and restaurants, and a doctor slew a burglar in his suburban home. By the end of the day, six banks had been robbed, a hundred shops had been looted, twelve fires had been set, forty carloads of storefront glass had been broken, and three million dollars in property damage had been inflicted, before city authorities had to call in the army and, of course, the Mounties to restore order. This decisive empirical test left my politics in tatters (and offered a foretaste of life as a scientist)."[16]
Apart from violence, there's another big thing that probably went missing, too - authorization for certain people to enter private property for reasons of the general good. The reason we call the police for welfare checks, for better or worse, is that nobody else has the right to enter your house. A doctor might be better suited to responding to someone undergoing a mental health crisis, but they can't break in. Similarly, you see stories of "police rescue deer from rooftop" or whatever because nobody else is authorized to climb onto random rooftops. If a society wants to get rid of the police, it needs to designate some other group to handle this use case. It can't simply get rid of the police.
A "natural experiment" of a world without police is quite unnatural: it's a world built up around the police with a sudden police-shaped gap in the middle.
To pick an analogy that should make sense to folks here, it's like shutting down your datacenter for 16 hours, suffering serious outages, and then concluding that your company absolutely needs its datacenter. Well, yes, it does today, but that's not what the people saying you should look at public cloud are advocating.
I'm not saying that Trump supporters should not be able to, but the anti-police crowd seem to not think far enough ahead to realize that taking power away from police and giving it to the people means giving it to people that they see as political and ideological enemies as well.
Edit: would someone like to dispute this instead of just downvoting? I'm trying to discuss in good faith; this seems to be a real problem with the idea of arming the populace: inevitably there will be citizens who have different ideas on self-policing their community. Would we only allow people with socially acceptable ideologies to have arms?
Also Trump supporters don't equal Pro 2A. Most of my USA based colleagues are Pro 2A, including the Biden supporters, and most are not Trump fans.
Also most people that I know with gun permits in my country (extremely rare) are more knowledgeable on laws than most policemen; same for gun training, we do train policemen in the range and we see that.
In a neighborhood where people are armed there is no need to patrol on the streets. Guess what is the place around the gun range that is never robbed? The gun range. People don't take risks, they pick the easy targets, gun-free zones are perfect targets for people that ignore the laws.
